Existing literature on cross-national variation in violence has paid little attention to the transnational transmission of crime. One such channel are the forced returns of migrants with a criminal record in their countries of temporary residence. Responding to this research gap, we study the effect of US deportations of convicts on levels of violent crime in deportees' countries of origin for a cross-country panel of up to 123 countries covering the years 2003 to 2015. We find a strong and robust effect of criminal deportations on homicide rates in countries of origin, that is to a large degree driven by deportations towards Latin America and the Caribbean. An additional inflow of ten deportees with a criminal history per 100,000 increases expected homicide rates by more than two. In addition to controlling for country-specific fixed effects, we provide evidence on a causal effect using an instrumental variable approach, that exploits spatial and time variation in migrant populations' exposure to state level immigration policies in the US.

出口谋杀案：美国的驱逐出境和暴力蔓延

关于跨国暴力变化的现有文献很少关注犯罪的跨国传播。一个这样的渠道是被迫返回其在其临时居住国有犯罪记录的移民。针对这一研究差距，我们在2003年至2015年的多达123个国家的跨国小组中研究了美国驱逐定罪犯对被驱逐出境国中暴力犯罪水平的影响。犯罪驱逐出境对原籍国凶杀率的影响，这在很大程度上是由对拉丁美洲和加勒比的驱逐出境驱动的。每10万名犯罪分子有10名被驱逐出境者的增加，使预期凶杀率增加了两倍以上。除了控制特定于国家的固定效果外，
